This invention relates to improvements in shoe construction and more particularly to improvements in the construction of open back shoes for ladies.

In each shoe of the open back type as made heretofore, the upper not only at the front of the shoe but also at the back extends around the edge of the insole and is secured beneath the insole in any suitable manner, between the insole and the outsole or between the insole and the heel. With this construction, throughout, the back part of the upper is not drawn closely around the foot of the wearer, and when the wearer rests her weight on the foot the upper bulges adjacent at the edge of the insole. Such bulging is very undesirable and produces an unsightly appearance.

An important object of this invention is to provide a novel and advantageous form of shoe construction which will obviate such disadvantages.

Another object of the invention is to provide an open back shoe in which the upper at the back of the shoe will fit closely around the lower parts of the sides of the foot of a wearer.

A further object of the invention is to provide an open back shoe in which the upper at. and near its back edge does not pass around the edge of the insole.

A still further object of the invention is to provide a shoe in which the upper at any exposed edge thereof extending upwardly from the insole will fit closely around the foot of the wearer.

The present invention may be applied to particular advantage, to various types of open back shoes, for example to an open back pump. v

Other objects, features and advantages will appear upon consideration of the following detailed description and of the drawing, in which Fig. 1 is a side elevation of an open back pump embodying the present invention;

Fig. 2 is a fragmentary bottom view illustrating a manner of slitting the insole and of inserting portions of the upper in the slits;

Fig. 3 is a fragmentary edge view of the insole illustrating the manner of slitting the same; and

Fig. 4 is a section taken along the line 4-4 of Fig. 1.

Referring to the drawing there is illustrated in Fig. 1 in side elevation an open back shoe I of the pump type embodying" the present invention. This shoe comprises an upper I I, an insole I2, an outsole I3, and a heel I 4. Between the insole and outsole is a shank stifiener I5, which may be of steel. The outsole I3 is split at its 5' Claims. (Cl. 36-495) 2 a rear end to provide a heel breast flap I6 to cover the breast of the'heel I4, and a portion to overlie the front part of the heel. At the back the upper is provided with a sling or sling arrangement II to hold the back part of the shoe on a foot. This sling comprises a, strap or strap portion I8 extending from the rear end of the front side of the upper (Fig. 1) around the back of the ankle and adapted to be connected to a buckle I9 on a strap or strap portion 20 extending rearwardly from the side of the upper at the rear in Fig. 1. These parts are well known to shoemakers and others skilled in the art.

At the front of the shoe the upper II is carried around the edge of ,the insole and secured between the insole and the outsole by suitable means, for example by paste or the like. At the back, however, it is preferable in carrying out this invention to carry the upper to the top surface of the insole and to secure the upper to the insole. Preferably this result may be attained by cutting or slitting the insole at each side so that at the edge of the insole a cut or slit 2|, to receive the rear edge of the upper, shows as a line extending from the upper part of the insole at the back part of the shoe downwardly and forwardly to the bottom of the insole. This cut is preferably so inclined as to come to the lower surface of the insole and form a tongue 2a which at its outer edge along the edge of the insole increases in thickness from front to rear and at its inner edge is very thin. With the insole thus prepared, the upper is passed between the tongue 22 and the body of the insole and after being placed in proper position, as by being drawn tightly around a last, is secured in such position in a suitable manner as by means of tacks or nails 23 securing the tongue and the adjoining portion of the upper to the main portion of the insole.

After the upper and the insole have been assembled on a last, the shank stiffener I5, the outsole I3 and the heel I4 may be added to the assembly, the parts may be pasted together or secured in another suitable manner. In the finished shoe the insole I2 may be covered by a; sock lining 23a attached thereto as by pasting.

Upon inspection of Fig. 4 it will be evident that upon drawing together the straps I8 and 20 and securing them by means of the buckle I9 the upper II at and near its rear edge will be drawn closely around the foot of the wearer and will obviate gapping or bulging such as is experienced where the rear portion of the upper passes around the edge of the insole. It is evident that this arrangement will be very effective for the purpose specified.

It should'be understood that various changes I may be made and that certain features may be i used without others, without departing from the true scope and spirit of the invention.

Having thus described my invention, I claim: 1. In an open back shoe the combination of I an upper having at each side a free rear edge extending upwardly from the sole of the shoe,

1 an insole having at each side'thereof a slit start- 1 ing at the rear of the shank, said slit extending forwardly and outwardly through the edge of the insole and inclining downwardly and inwardly to provide a tongue having a substantial width at the edge of the insole and an edge having at the and decreasing in thickness to a forward edge at 2. The combination according to claim 1 wherein said slit extends forwardly and then outwardly,

3. The combination according to claim 1 wherein said slit extends along a curved line.

- 4. In an open back shoe, the combination of an upper having at each side an exposed rear edge, an insole having through each edge a slit providing a tongue having at the edge of the insole an edge starting at the back with a thickness equal substantially to that of the insole and decreasing gradually to nothing at the front and having a thin inner edge," the upper at the forward portion of the shoe passing around the edge of the insole and the back portion passing into 4 said slit and to the upper surface of said tongue,

3 rear thereof a thickness equal to that of the insole i I the lower surface of the insole, said upper being secured in said slit and extending from the hot- 1 tom face of said insole upwardly through said 1 Slit.

side of the insole. and receiving the corresponding upper element and means for securing each element in the corresponding slit; I SALVATORE CANGEMI.
